electro-, electr-, electri-

The potential electrical differences observed from leads applied to the surface of the cerebral cortex.

A specialist in the science or medical field who measures and records brain waves with electrodes which are positioned at the cerebral cortex.

A written recording of the measurement of brain waves through electrodes placed at the cerebral cortex.

A descriptive term referring to the measurement and recording of brain waves through electrodes placed at the cerebral cortex.

1. A recording of the electrical impulses from the brain by electrodes placed directly on the cerebral cortex.
2. The process of recording the electric activity of the brain by electrodes placed directly on the cerebral cortex, providing a much higher voltage, greater accuracy, and more exact localization than electroencephalography.

A steroid secreted by the cortex of the adrenal gland.

It is the strongest hormone regulating the body's electrolyte balance.

Aldosterone acts directly on the kidney to decrease the rate of sodium-ion excretion (with accompanying retention of water), and to increase the rate of potassium-ion excretion.

The primary function of aldosterone is the regulation of electrolyte metabolism, that is, promotion of sodium retention and enhancement of potassium excretion.

1. The use of electricity to stimulate the growth of plants for crops.
2. The stimulation of the growth, development, and maturing of plants by electrical procedures; especially, by static electricity and the fields of forces in the atmosphere.

1. To cause injury or death with an electric shock.
2. To execute someone by means of the electric chair.

The destruction of life by means of electric current.

An executioner who uses electricity to kill the legally convicted person who has been condemned to die.

A recording of electric currents or changes in electric potential from the urinary bladder.

1. A solid electric conductor through which an electric current enters or leaves an electrolytic cell or other medium.
2. A collector or emitter of electric charge or of electric-charge carriers, as in a semiconducting device.
3. A conducting element that performs one or more of the functions of emitting, collecting, or controlling the movements of electrons or ions in an electron tube, or the movements of electrons or holes in a semiconductor device.
4. A medium for conducting an electrical current from the body to physiological monitoring equipment.
5. A terminal or surface at which electricity passes from one material or medium to another, as at the electrodes of a battery or electrolytic capacitor.
6. One of the terminals of metal, salts, or electrolytes through which electricity is applied to, or taken from, the body or an electric device or instrument.
7. An electronically conductive structure that provides for an electrochemical reaction through the change of oxidation state of a substance.

It may contain or support the reactant or act as the site for the reaction. The anode and cathode of an electric cell are electrodes.

A boiler that converts electricity to heat energy, by passing a current between electrodes immersed in water to raise the temperature of the water.

The current that flows in a photodetector when there is no optical radiation incident on the detector and operating voltages are applied.

A jelly used for improving the contact between the skin and an electrode during an examination utilizing electrocardiography and electroencephalography.
